Esch channel is provided with a series of gas ducts or nozzles which respectively enter the hottoms oi the series/of fines onthe seine side ci' the centerline as the aforesaid channel. While one group of ilues is ope-ratingl as uphurning fines and is receiving n supply of fuel Igras from the gas channel lli located in the pillar wall beneath. the heating wall, the other group of tlues in the sonic heating wall is concurrently operating to direct the rlownow from the first nientioned Pgroup of lines into the regeneratorsv located below the clownlow operating lines. 'The usual reversing connections cre provided for turning on the flow of gas into the chnnnelswhich supply the npburning iiues and for cutting oil' the iow oitl gas into the gas channels 18 which communicate with the .lowndraiit fines; l,

yunderstood that the" inflow operating regenerators deliver preheated outside air supplied through the air boxes 26tothe up- Vhm-ning flues and that the outflow operating v regenerators receive the products of combustion from the downdraft flues and convey such products of combustion to the Waste gas tunnel 27 leading to the stack. The

tops of the respective regenerators 23 com! 'iinunicate with the lines 17 by meansof ducts .28, there being a ,series of such ducts conneeting the top of each regenerator with vits corresponding group of lues located on l5 the same sidev of the central longitudinal line 24., Y The present invention is chiefly 'concerned with the provision of, a novel system for controlling the tlow through 'the several regenerators and lues whereby7 the flow through the vinterior portions or the regenerators and those lues which are located in the interior portion of the battery is equalized with respect to the less remote portions of 'the regenerators andthe less remote fines, both of which adjoin the sides of the battery. It is desirable to equalize the flow throughout each regenerator and throughout the entire group 4of ilues With Which-it communicates, I in order to obtain .uniform heat conditions throughoutV the entire battery structure. Such equalizing of.

the flow is a. problem of no inconsiderable diiiiculty, not 'only because of the great size of the regenerators themselves but also Ibecause of the fact that those flame lues which are located in the longitudinal central portion ofthe oven are more remote from the aoregenerators than l sides of the oven,

from the stack tunnel 27 than the last men- ,tiorred Hues. It is consequently necessary t`o vary the draft in these more remote lines order t0 equalize the volume of 'flow entering' those dues with that entering ithe fines which adjoin the sides of the battery and are consequently located nearer the `points of supplyjor the points of discharge. I H #A The above mentimie'd equalizingjof 'flow throughout the regenteiat/ors and the ues is y accomplished by' the present invention in l" the following. 'manner' The' checkerworlr 1% of each l'regenerato'rf is divided into a plurality of comparments 29 'cal partitioned@ connecting together tlie the iiues ladjoining the pillar Walls lfition the opposite sides 'o- Thus divided, each coin#A such regenwater-'k y partmentlpf "the regenerator checleiworl controls the 1now through a subgroup ot. of. the entire group of dues corresponding to and conmctedwrth such re erlernten in individual lovyij'hiay thus e 'maintained '65 in each compartment and theV in the lt will be' spective regencrators,

and are also more remotey be noted that the outermost .means of three of'such by meansor vertiL i As shown in the drawings, the series of 75 regenerators on each side of the battery'are Idivided into groups, there being in the present instance eight regenerators parallel with each other in each group. Located in 'the bottom of each of such regenerators are three crossvviseextending sole channels 31, which however, extend-to and open up into' only one of the compartments 29 of their re- Assuming that the lthree sole channels 3i in the bottom of the 85 regenerator at one end of the group of such regenerators extend to and open up intothe innermost compartment 29 ot' that regenerator7 the f'corresponding three sole channels 3l of the nent adjacent regenerator extend 90 to and open up into the compartment nent" to the innermost compartment of their corresponding regenerator. Similarly, the three sole channels 3l of the other regenerators taken seriatim, extend respectively to and open up into compartments 29 of their regenerators which are next less remote than the compartments 29 connected with the channels 31. of the preceding regenerators. The result is that the sole channels 3l of the leu regenerator at one end of the group lead to the innermost compartment 297 Whereas the sole channels 3l of the' regenerator at the other end of the group lead to the outermost compartment 29, as shown in Eig. 2L It will 105 compartments 29 of all the regenerators are of much less depth than the other compartments of such regenerators. y f

Above the before-mentioned erossvvise-eX- tending sole channels 31 are longitndinallyextending connection channels 32. These connection channels 32 connect together all of the compartments of the several regenera tors of each group of regenerators which of the saine degree of rem'oteness in their respective regenerators. Thus all ofthe most remote compartments 29 of each entire group of regenerators are interconnected by longitudinallyextending connection channels 32; the next remote series ot vcompartinents of the entire group of regenerators are similarly interextendi g channels 329 and` so will be, noted9 however, that the lseveral compartments 29 ineach group of 'egenerators that thedea'st remote from the side of the battery are1--interconnected hyonly two ot said connection chanconnectd hv three ot such longitudinallyare 11e l nels 32, because off-the .depth oi such compartments. i

Esch group oi three cross'wiseeiztending "sole channels 3l, of each group or regenerators, entends to the longitudinal connection channels 32 ofthe `compartruents 'with which such-group of crosswise-eiitending sole channels connects, Thus the ilow of the 'several compartments of' one 'degree of remoti-mess in 'from tlieside of the battery in euch group of regenerstors may he controlled by tlie flow in a single 1 group oi crosswise-extending. channels 8l independently ci e 'series of compartments of another degree ci rc- ;5 mote-ness in the saine group ci regeneretors,

With the foregoing construction, coupled with .the individuel ndjustsbility of the severel oir bon lids 33 and the severe-l outflow dempers Se, it is possible to regulate the in 'draft conditions in all` parte of the oven or buttery/.in e manner to equalize the lovv in ell perte of the battery, notwithstanding the diderent degrees oi remoteness which diierent perte of the battery hear to the points 55 of eirsupply and the points of dischzirgeof exlioust gases. For example, as the lid and demper of a single sir box control the flow to the entire series of regenerative compartments 29 oi the same degree of remotcness 60 of each entire group of regenerators, the

draft in all of the regenerative compart- I ments and to all of the Huss with whichv `such compartments communicate may he equelized and adjusted .relatively to the es drsfl't'in 4another series or mmpertments of r. v .mortero dirle-rent degree, of remoteness, so es to vary the draft in different portions oi the oven in. e Ivey that will equalize the throughout the oven es s Whole.
